2. Ground source heat pump - Wikipedia

   en.wikipedia.org/wiki/Ground_source_heat_pump

   A heat pump in combination with heat and cold storage. A ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that use a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons.

   That heat can be extracted with a geothermal heat pump more efficiently than it can be generated by conventional furnaces. [10] Geothermal heat pumps are economically viable essentially anywhere in the world. In theory, geothermal energy (usually cooling) can also be extracted from existing infrastructure, such as municipal water pipes. [14]

   DX system being drilled in the 1980s. A direct exchange (DX) geothermal heat pump is a type of ground source heat pump in which refrigerant circulates through copper tubing placed in the ground unlike other ground source heat pumps where refrigerant is restricted to the heat pump itself with a secondary loop in the ground filled with a mixture of water and anti-freeze.

7. Ground-coupled heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

   A slow drip watering system may improve thermal performance. Damp soil in contact with the cooling tube conducts heat more efficiently than dry soil. Earth cooling tubes are much less effective in hot humid climates (like Florida) where the ambient temperature of the earth approaches human comfort temperature.
